Of the fine plant now illustrated, there are two distinct varieties: one having 
a white lip with a crimson spot as figured in our plate, and in those quoted 
above; the other, most commonly known in gardens as FH. macrochilwm rosewm, 
having a pretty rose-coloured lip, as figured by Bateman in his splendid Orchidacee 
of Mexico and Guatemala, by Reichenbach in Pescatorea, by Paxton in the Magazine 
of Botany, and by Van Houtte in the Flore des Serres. Both forms are exceed- 
ingly beautiful. 
We are indebted to Baron Schréeder for our present figure, the drawing for 
which was made by our artist from a plant in the grand collection cultivated at 
The Dell, Staines. 
Epidendrum atropurpureum is an evergreen plant with pear-shaped pseudobulbs 
of a light green colour. The foliage grows about ten inches or a foot high, and 
the flower-spike proceeds from the top of the pseudobulb during the winter and 
spring months after the bulbs have. completed their growth. The sepals and petals 
are of a deep reddish purple, and the lip is white, with a distinct purple-crimson 
blotch in the centre; it continues in bloom for several weeks and is worthy of a 
place in every collection, for, as Mr. Ballantyne says, it is most useful and takes 
up so little room. 
This plant will do either in a basket or on a block suspended near the light, 
and slightly shaded from the burning sun. It is found growing in exposed situations, 
and the bulbs require to be well matured in order to induce them to bloom freely. 
If grown in baskets the material we recommend for the roots is good fibrous peat 
and sphagnum moss, with good drainage. They require but little soil, but they 
seem to enjoy a few lumps of charcoal on the surface of the peat. If grown on 
blocks some live sphagnum moss applied during the period of active growth helps to 
keep them moist about the roots during warm weather when their growth is pro- 
gressing; the blocks must be syringed every day in hot weather. ‘The Cattleya 
house is the most suitable locality for them. When the plant is found to be doing 
well and rooting freely, do not on any account disturb it, as it dislikes being cut, 
and if the back bulbs are cut they seldom break or do any further good. Some 
Orchids will stand being disturbed, while in other cases it causes them to dwindle — 
away. 
CattLeya Mossta Porrsu.—This is a most lovely variety of an old favourite, 
and was bloomed in June this year by Arthur Potts, Esq., Hoole Hall, Chester, after 
whom it is named. We must congratulate Mr. Potts on being so fortunate as to 
bloom such a gem. The flower is about seven inches in diameter, the petals beimg 
broad and flat, blush, beautifully feathered in the centre with a broad band of 
magenta-purple of a most irregular form; the sepals are irregularly marked in the 
same way; the lip is large and broad, deep magenta-purple, broadly ‘margined with 
blush white, and with a yellow throat. The effect of the pale margin of the lip 
against the deep colouring of the segments is most charming.—B. S. W.
